    Survival curves of days from device removal to pregnancy in primiparous and multiparous cows not inseminated by 60 DIM, but subsequently treated with a progesterone-releasing intravaginal device (PRID

    Survival curves of days from device removal to pregnancy in primiparous and multiparous cows not inseminated by 60 DIM, but subsequently treated with a progesterone-releasing intravaginal device (PRID) or placebo intravaginal device (control) for 7 d and receiving a single dose of PGF2α and inseminated after observed estrus.
